Filter Intake/Outlet Positioning - 300 gallon tank

[danotaylor]

The rate of return determines the rate the water flows over the weir.
There’s quite a few folks that plump canisters to their sump intake/return holes.
The intake drain standpipe height will determine the water level behind the weir. Providing you have your water levels set appropriately, achieved by filling the main tank w all pumps off, let it overflow into sump to 2” from top of sump, then turn faucet off. This will prevent your sump overflowing as water drains during a power outage. Once set, turn pumps on and the sump will drain some as the main tank fills. Once water is recirculating, you can draw a fill line in your sump. This line is where you can safely fill to if you leave the pumps running

Awesome. I appreciate the help brother you saved me a huge headache of trying to hide my intakes.

I’ll probably move forward with one fx6 like you mentioned. If I for whatever reason decide I need another I can just follow the same process.

Hi danotaylor ,

Just a quick follow up. I’ve been working to set up this tank slowly but surely and I got my sump setup and placed the fx6 intake behind the weir as we spoke about.

One thing I didn’t consider is the fx6 has an auto-restart feature that kicks in every 12 hours to purge air.

It’s happened a couple times now, but do you think it’s possible that it’s messing with my drain/return alignment?

I have a herbie setup and I feel as though in the day I have it tuned but once the filter resets it goes back to need some small tuning.

Do I need to move the intake into the display to solve this? Should I just ditch the fx6 entirely?
